Process for the production of a polyolefin-based composite material of high rigidity

The invention relates to a method for preparing high buprenorphine, comprising the polyolefin and laminated clay the method of polyolefin base composite material, wherein the method is an alkyl cationic further intercalated laminated, a swell clay of the monomer according to at least one to any one of agent, and wherein the clay and polyolefin and 5-40% of the filtering, is higher than the polyolefin is the melting point temperature is mixed. The invention further relates to a method for high rigid of polyolefin composite material, wherein said composite material comprises 98-50% by one of homopolymers or the copolymer of the 1-50% of derivative according to weight laminated clays, ratio of the is under the polyolefin melting point low temperature 30℃, wherein the material the elasticity modulus of raw material polyolefin ratio of this modulus is greater than or equal to 1.
